Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66748, here are decompositions:
- 47 + 66701 = 66748
- 131 + 66617 = 66748
- 179 + 66569 = 66748
- 239 + 66509 = 66748
- 257 + 66491 = 66748
- 281 + 66467 = 66748
- 317 + 66431 = 66748
- 389 + 66359 = 66748
Showing the first eight; more decompositions exist.
